Does 2017 Jeep Cherokee Trailhawk Require Special Wiring Harness When Flat Towed

Yes, when flat towing your 2017 Jeep Cherokee Trailhawk you have to install the wiring kit 68321424AB which you can only get from a Jeep dealer. This harness is designed to address a "wobble" or steering issue that occurs sometimes when the vehicle is flat towing. The newer Cherokee 4x4's have electric power steering. Many people reported a severe shaking/wobble while towing over rough roads. Jeep issued a Service Bulletin which calls for a special wiring harness which keeps the PS energized while being towed.

The custom base plate kit you need is part # RM-521447-5. This will connect directly to the Falcon 2 tow bar, part # RM-520. Then you can use part # RM-643 for safety cables.

To power the Jeep's lights I suggest the diode kit # RM-15267. This will use the vehicle's tail lights by connecting to the RV's and includes the cord to go between the two. To keep the battery topped off when flat towing you'll also want the part # RM-156-25 which will charge it when being towed.

For a supplemental braking system the Stay-IN-Play DUO # SM99251 is a favorite around here because of how reliable it is and it's easier to install than many other permanently installed systems. You should use a stop light switch kit, part # RM-751471 to monitor the DUO.

Finally, you'll likely need a high-low adapter. I've attached an article to help you determine the correct rise or drop your setup requires. I've also linked our selection of adapters for you to look at once you know what you need.

In addition to my recommendations I've linked some articles on flat towing that you may find helpful.
